DEVICE FOR CLEANING CUT-OFF WIRES OF BRICK-MACHINES SPECIFICATION forming part of Letters Patent No. 318,055, dated May 19, 1885.

Application filed December 23, 1884. (No model.)

To aZZ whom-it may concern.-

Be it known that I, JOHN N. TRIOKER, a citizen of the United States, residing at the city and county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Devices for Cleaning Cut-Off Wires of Brick-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of this invention is to provide a means for mechanicallyremoving small roots, grass, and other obstructions that accumulate upon the wires of that class of brick-machines in which a bar of clay is severed into bricks by a series of wires caused to pass transversely through the bar of clay. Although adaptable to other machines in which bars of clay are cut off by means of wires, it is more especially adapted to be used in connection with the out off wires of the brick-machine shown and described in Letters Patent N 0. 297,671, granted to Cyrus Chambers, Jr., on the 29th day of April, 1884, to which reference may be had.

The invention consists in the combination, with the wire cut-off device shown in said patent, of a brush placed so that the wires in their movement come into contact therewith, whereby the obstructing accumulations above alluded to are swept off the wires, as hereinafter more particularly set forth.

Of the accompanying drawings, Figure 1 is a side elevation of a portion of the endless cut-off belt system of said patent having the cutoff wires mounted thereon with my cleansing brush in combination therewith. Fig. 2 is a plan view of the same, showing a modification of the invention. Fig. 3 is a plan View of the brush, Fig. 2, and the adjustable arms in which the same is journaled detached.

A is the endless cut-off belt running over a pulley, B, and also over another pulley. (Not shown in the drawings.) To this belt are secured plates B, to which are fastened the U- shaped elastic bows U,which sustain the cutoff wires E. Said belt is driven by suitable mechanism in the direction of the adjacent arrow in Figs. 1 and 2, and it is placed with re lation to the bar of clay which is expressed from the die of the brick-machine so that as it moves forward, the wires, after passing around the pulley 13, enter the clay bar successively, and finally sever the same into bricks, as particularly described in the aforesaid patent of Cyrus Chambers, Jr.

Heretofore small roots of grass and other obstructions contained in the clay clinging to the cut-off wires after the latter passes through the bar of clay and interfering with the efficiency of the cutoff had to be removed by the hand, observing which led me to contrive and to apply the automatic cleaning device now to be described. It consists of a cylinder, D, studded with bristles q, of wire, wool, or similar material, constituting a brush, C. This is mounted on a journal, J, which runs in bearings G at the ends of two arms, K, secured to the sides, respectively,of theframe L, in which pulley B is journaled, and is arranged so that the wires as they round the pulley come successively into contact with the periphery of the brush, as seen in Figs. 1 and 2. By this means the filaments, 820., which may clog the wires areremoved.

Although not essential it is preferable to arrange the device somewhat obliquely to the cut-off wires,as shown in the drawings,whereby the tendency is for the brush to work the obstructions on the wires endwise-that is, from that side of the latter which first comes into contact with the brush toward the portion that follows. I also provide means for rendering the brush adjustable with relation to the cut-off wires,which in the present instance consistsin attaching the arms K, at the outer ends of which the brush is j ournaled, to the frame L by means of bolts M, passing through slots N, Fig. 1, in the said arms. In this way, it will be observed, the brush may be set so that the wire will come more or less closely or forcibly in contact with the former. It is not absolutely necessary that the brush should be freely rotatable by the force of the cut-off wires coming into contact therewith; but it may be arranged so that it can be turned when desired, so as to bring another part of its periphery into the path of the wires in place of the portion previously in use which may have become worn out.

In the modification illustrated in Figs. 2 and 3 the brush, instead of being rotated by the action of the out off wires impinging Too of the brush mounted obliquely to the path of said wires, substantially as and for the purpose described.

3. The combination, with the cut-0H wires, of the brush, with means for adjusting the same with relation to the said wires, substantially as and for the purpose set forth.

7 In testimony whereof I have hereunto affixed my signature this 20th day of November, A. D. 1884:.

JOHN N. TRICKER.
